Specific compounds of general formula I are described in the examples.

In addition to these compounds of general formula 1, if a nitrogen atom is contained in R⁷, this invention also relates to their physiologically compatible addition salts with organic and inorganic acids, pharmaceutical preparations that contain these compounds of general formula I inclusive of the addition salts as well as their use for the production of pharmaceutical agents.

Inorganic and organic acids, as are known to one skilled in the art for the formation of physiologically compatible salts, are suitable for the formation of acid addition salts. As addition salts with acids, especially hydrochlorides, hydrobromides, acetates, citrates, oxalates, tartrates and methanesulfonates can be cited.

The compounds of general formula I represent compounds with strong antiestrogenic action.

The compounds according to the invention are either pure antiestrogens or so-called partial antagonists, i.e., antiestrogens with partial estrogenic action such as tamoxifen or raloxifen. In contrast to the tamoxifen, their agonistic, estrogenic action is expressed in a tissue-selective manner in the case of partial antagonists of general formula I. In particular, the agonistic action occurs in bone, in the cardiovascular system and in the central nervous system. In particular, no action or only slightly agonistic action occurs in the uterus.

Compounds with antiestrogenic properties, i.e., substances with inhibiting actions compared to estrogens have already been described extensively.

As the compounds that come closest structurally to these compounds of general formula I, the steroid derivatives that are known from EP 0 138 504 B1 can be considered. The 7α-[9-(4,4,5,5,5-pentafluoropentylsulfinyl)-n-nonyl]-estra-1,3,5(10)-triene-3,17β-diol (EP-A 0 138 504, page 58, penultimate compound) is currently under clinical development for hormone-dependent tumors (breast cancer) and represents the compound that is best known at this time, i.e., the one with the strongest antiestrogenic activity, of these steroid derivatives.

Pharmaceutical compositions, which contain sex steroid inhibitors, which have a steroidal skeleton that has a 7α-side chain in the case of the simultaneous presence of at least one other substituent in 14-, 15- or 16-position, are the subject of EP-A 0 376 576.

A considerable number of the most widely varied compounds—i.a. those of steroidal origin and those with a 2-phenylindole skeleton—which act as antiestrogens and/or suppress the estrogen biosynthesis, are disclosed in WO 93/10741.

Other steroidal antiestrogens, which carry an 11β-phenyl radical, are described in EP-AS 0 384 842 and 0 629 635.

Compounds according to the invention are antiestrogens with mostly stronger antiestrogenic action than the already mentioned 7α-[9-(4,4,5,5,5-pentafluoropentylsulfinyl)-n-nonyl]-estra-1,3,5(10)-triene-3,17β-diol and/or compounds that are distinguished from 7α-[9-(4,4,5,5,5-pentafluoropentylsulfinyl)-n-nonyl]-estra-1,3,5(10)-triene-3,17β-diol by their partial estrogenic action.

The compounds of general formula I according to this application are distinguished by the additional 11β-fluorine atom in comparison to the already known steroid derivatives according to EP-A 0 138 504 and EP-A 0 367 576.

This structural modification is of decisive importance for the advantageous properties of the compounds according to the invention.

The antiestrogenic action of the compounds according to the invention was determined in transactivation assays [Demirpence, E.; Duchesne, M.-J.; Badia, E.; Gagne, D. and Pons, M.: MVLN Cells: a Bioluminescent MCF-7-Derived cell Line to Study the Modulation of Estrogenic Activity; J. Steroid. Molec. Biol. Vol. 46, No. 3, 355-364 (1993) and Berry, M.; Metzger, D.; Chambon, P.: Role of the Two Activating Domains of the Estrogen Receptor in the Cell-type and Promoter-context Dependent Agonistic Activity of the Anti-estrogen 4-Hydroxytamoxifen; The EMBO Journal Vol. 9, 2811-2818 (1990)].

The MVLN cells are transfixed in a stable manner with reporter gene Vit-TK-LUC. The antiestrogenic active strength was determined in the presence of 0.1 nM of estradiol.

The IC₅₀ values for the new compounds are in the nanomolar range. In the MVLN cell line, the following IC₅₀ values are produced for the compound of Examples 3 and 8 (execution of test according to the above-indicated bibliographic references):

IC50 [nM] IC50 [nM] Compound MVLN HeLa Example 3 6.3 0.2 Example 8 37 8

The uterus growth test in infantile rats, p.o. (test on antiestrogenic action in vivo) also confirms the antiestrogenic action of the compounds according to the invention. The test was performed as described below:

Uterus Growth Test in Infantile Rats (Antiestrogenic Action)

Principle of the Method

In rodents, the uterus reacts to the application of estrogens with an increase in weight (both proliferation and water retention). This growth can be inhibited in a dose-dependent manner by simultaneous administration of compounds that have an antiestrogenic action.

Execution of the Test

Animals:

Infantile female rats weighing 35-45 g at the beginning of the test, 5-6 animals per dose.

Formulation and Administration of the Substances:

For the p.o. administration, the substances are dissolved in 1 part ethanol (E) and made up with 9 parts peanut oil (EÖ).

Test Batch

The young rats just dropped by the mothers are delivered for acclimation one day before the beginning of treatment and immediately supplied with food—right in the cage. The treatment is then carried out once daily over 3 days in combination with 0.5 μg of estradiol benzoate (EB). EB is always administered subcutaneously (s.c.), while the test substance is administered p.o. (perorally). 24 hours after the last administration, the animals are weighed, killed and the uteri are removed. The moist weight (less contents) is determined from the prepared uteri.

Controls

Negative control: Vehicle (E/EÖ), 0.2 ml/animal/day

Positive control: 0.5 μg of EB/0.1 ml/animal/day

Evaluation

The average values are determined with standard deviation (X+SD) and the significance of the differences in the control group (EB) in the Dunnett Test (p<0.05) for each group from the relative organ weights (mg/100 g of body weight). The calculation of the inhibition (in %) compared to the EB-control is carried out with a program. The relative actions of the test substances are determined by co-variance analysis and regression analysis.

As pure antiestrogens for the purposes of this invention, those compounds of general formula I that show no action or, in the best case, only slightly agonistic action, i.e., an agonistic action up to about 20% of the action of estradiol, in the in-vitro test on estrogenic action that is described below can be considered.

Partial Estrogenic Action

The transition between the pure antiestrogens and the partial agonists, the tissue-selective estrogens, is seamless. Compounds that have a slightly agonistic action can also be used in the indications that are mentioned below for pure antiestrogens.

The partial estrogenic action of compounds according to the invention was determined by transactivation assays. HeLa cells were transfixed with human estrogen receptor expression vector (HEGO) and a reporter gene rPR-TK-CAT. This reporter gene contains the “Estrogen Responsive Element” of the rabbit progesterone receptor gene (+698/+729 region) before a TK-CAT gene (Savouret, J. F.; Bailly, A.; Misrahi, M.; Rauch, C.; Redeuilh, G.; Chauchereau, A.; Milgrom, E., Characterization of the Hormone Responsive Element Involved in the Regulation of the Progesterone Receptor Gene. EMBO J. 10, 1875-1883 (1991).

The estrogenic action was determined at a concentration of 1 μm.

The compounds according to the invention, especially if they are pure antiestrogens, are suitable for treatment of estrogen-dependent diseases, for example breast cancer (second-line treatement of tamoxifen-resistant breast cancer; for adjuvant treatment of breast cancer instead of tamoxifen), endometrial cancer, prostate cancer, prostatic hyperplasia, anovulatory infertility and elanoma.

In addition, the pure antiestrogens of general formula I can be used as components in the products that are described in EP 346 014 B1 which contain an estrogen and a pure antiestrogen, specifically for simultaneous, sequential or separate use for selective estrogen therapy of peri- or postmenopausal women. The compounds of general formula I, especially if these are pure antiestrogens, can be used together with antigestagens (competitive progesterone antagonists) for the treatment of hormone-dependent tumors (EP 310 542 A).

Other indications in which the compounds of the general formula can be used are male hair loss, diffuse alopecia, alopecia that is caused by chemotherapy as well as hirsutism (Hye-Sun Oh and Robert C. Smart, Proc. Natl. Acad. Sci. USA, 93 (1996) 12525-12530).

In addition, the compounds of general formula I can be used for the production of medications for treating endometriosis and endometrial carcinomas.

The compounds of general formula I can also be used for the production of pharmaceutical compositions for male and female birth control (male birth control: DE-A 195 10 862.0).

The compounds of general formula I with tissue-selective partial estrogenic action can be used primarily for prophylaxis and treatment of osteoporosis and for the production of preparations for substitution therapy in pre-, peri- and post-menopause (HRT=hormone replacement therapy) (Black, L. J.; Sato, M.; Rowley, E. R.; Magee, D. E.; Bekele, A.; Williams, D. C.; Cullinan, G. J.; Bendele, R.; Kauffman, R. F.; Bensch, W. R.; Frolik, C. A.; Termine, J. D. and Bryant, H. U.: Raloxifene [Lyophilizate 139481 HCl] Prevents Bone Loss and Reduces Serum Cholesterol without Causing Uterine Hypertrophy in Ovariectomized Rats; J. Clin. Invest. 93: 63-69, 1994).

The invention also relates to pharmaceutical preparations that contain at least one compound of general formula I (or physiologically compatible addition salts with organic and inorganic acids of them) and the use of these compounds for the production of pharmaceutical agents, especially for treating estrogen-dependent diseases and tumors and pharmaceutical agents for hormone replacement therapy (HRT).

The compounds according to the invention and the acid addition salts are suitable for the production of pharmaceutical compositions and preparations. As active ingredients, the pharmaceutical compositions or pharmaceutical agents contain one or more of the compounds according to the invention or their acid addition salts, optionally mixed with other pharmacologically or pharmaceutically active substances. The production of the pharmaceutical agents is carried out in a known way, whereby the known and commonly used pharmaceutical adjuvants and other commonly used vehicles and diluents can be used.

As such vehicles and adjuvants, for example, those are suitable that are recommended or indicated in the following bibliographic references as adjuvants for pharmaceutics, cosmetics and related fields: Ullmans Encyklopädie der technischen Chemie [Ullman's Encyclopedia of Technical Chemistry], Volume 4 (1953), pages 1 to 39; Journal of Pharmaceutical Sciences, Volume 52 (1963), pages 918 and ff.; issued by Czetsch-Lindenwald, Hilfsstoffe für Pharmazie und angrenzende Gebiete [Adjuvants for Pharmaceutics and Related Fields]; Pharm. Ind. Issue 2, 1961, pages 72 and ff.; Dr. H. P. Fiedler, Lexikon der Hilfsstoffe für Pharmazie, Kosmetik und angrenzende Gebiete [Dictionary of Adjuvants for Pharmaceutics, Cosmetics and Related Fields] Cantor K G, Aulendorf in Württemberg 1971.

The compounds can be administered orally or parenterally, for example intraperitoneally, intramuscularly, subcutaneously or percutaneously. The compounds can also be implanted in the tissue. The amount of the compounds to be administered varies within a wide range and can cover any effective amount. Based on the condition to be treated and the type of administration, the amount of administered compound can be 0.1-25 mg/kg of body weight, preferably 0.5-5 mg/kg of body weight, per day. In humans, this corresponds to a daily dose of 5 to 1250 mg. The preferred daily dosage in humans is 50 to 200 mg. This is true especially for tumor therapy.

For oral administration, capsules, pills, tablets, coated tablets, etc., are suitable. In addition to the active ingredient, the dosage units can contain a physiologically compatible vehicle, such as, for example, starch, sugar, sorbitol, gelatin, lubricant, silicic acid, talc, etc. The individual dosage units for oral administration can contain, for example, 5 to 500 mg of active ingredient.

To achieve better bio-availability of the active ingredient, the compounds can also be formulated as cyclodextrin clathrates. For this purpose, the compounds are reacted with α-, β- or γ-cyclodextrin or derivatives thereof (PCT/EP95/02656).

For parenteral administration, the active ingredients can be dissolved or suspended in a physiologically compatible diluent. As diluent, very frequently oils with or without the addition of a solubilizer, a surfactant, a suspending agent or emulsifier are used. Examples of oils that are used are olive oil, peanut oil, cottonseed oil, soybean oil, castor oil and sesame oil.

The compounds of general formula I can also be formulated in the form of a solution that is determined for oral administration and that in addition to the active compound of general formula I contains

a) a pharmaceutically compatible oil and/or

b) a pharmaceutically compatible lipophilic surfactant and/or

c) a pharmaceutically compatible hydrophilic surfactant and/or

d) a pharmaceutically compatible water-miscible solvent.

In this respect, reference is made in addition to WO 97/21440.

The compounds can also be used in the form of a depot injection or an implant preparation, which can be formulated in such a way that a delayed release of active ingredient is made possible.

As inert materials, implants can also contain, for example, biodegradable polymers or synthetic silicones such as, for example, silicone gum. In addition, the active ingredients can be embedded in, for example, a patch for percutaneous administration.

For the production of intravaginal systems (e.g., vaginal rings) or intrauterine systems (e.g., pessaries, spirals) that are loaded with active compounds of general formula I, various polymers such as, for example, silicone polymers, ethylene vinyl acetate, polyethylene or polypropylene are suitable.

The compounds according to the invention can be produced as described below. The examples below are used for a more detailed explanation of the invention. Other compounds of general formula I can be obtained by an analogous procedure using analogous reagents in the data contained in the examples.

As processes to create side chain R⁷ in the compounds according to the invention, especially also the methods of side-chain introduction and side-chain build-up that are described in EP 0 138 504 B1 are suitable, whereby then as a starting compound, instead of Δ⁶-nortestosterone, its 17-hydroxy group is acylated, and the 11β-fluorine compound 11β-fluorine-Δ⁶-androstenedione can be used. The reduction of the 17-keto group then takes place in a later stage.

The compounds of general formula I, in which R³¹ is a radical of formula —C(O)R³³, can be converted by complete reduction of the keto group of the carboxylic acid amide with lithium aluminum hydride or similar reducing agents according to the method that is familiar to one skilled in the art into the compounds in which R³¹ is then —CH₂—R³³.

A thio bridge in the side chain can be oxidized with sodium periodate into sulfoxide (Example 24n)); the sulfones are obtained from the sulfides with a peracid as an oxidizing agent, e.g., m-chloroperbenzoic acid.

The saponification of the ester groupings as well as esterification and etherification of free hydroxy groups is carried out in each case according to established processes of organic chemistry. By observing the various reactivity of the esterified and free 3- and 17-hydroxy group, the 3,17-diester can be cleaved selectively in 3-position, and the 3-hydroxy-17-acyloxy compound can then be additionally functionalized specifically in the 3-position; it is equally possible to esterify or to etherify the 3,17-dihydroxy compound selectively only in the 3-position and then to introduce specifically another radical into the 17-position as already in the 3-position.

The acid addition salts of the compounds of general formula I can also be produced from the compounds of general formula I according to standard processes.

The examples below are used for a more detailed explanation of the invention:

EXAMPLES Example 1 11β-Fluoro-7α-{5-[methyl-(8,8,9,9,9-pentafluoro-nonyl)-amino]-pentyl}-estra-1,3,5(10)-triene-3,17β-diol

a) 11β-Fluor-estr-4-ene-3,17-dione

4.6 ml of perfluorobutane-1-sulfonic acid fluoride is added in drops to 5.0 g of 11α-hydroxy-estr-4-ene-3,17-dione in 100 ml of toluene and 7.3 ml of 1,8-diazabicyclo[5,4,0]undec-7-ene at 0° C. After 30 minutes, the solution is diluted with ethyl acetate, washed with saturated sodium chloride solution, dried and concentrated by evaporation in a vacuum.
